Can I amend my 1040 Form to a 1040NR Form during my ID Verification process?

I Filed my taxes and realised that my 1040 is not the 1040NR that I need. I was in the US as a J-1 visa holder. I am trying to verify my ID now to the IRS. The question is if I can send them my amended 1040NR Form with all the papers they need to verify my ID?
